Most of us, with a little luck, will grow old. For some it’s an adventure, for others, a challenge — and for most — a bit of both. Our county has the oldest population in the Bay Area, aging more than one-and-a-half times faster than the rest of the state. By 2030 more than 33% of Marin’s citizens will be over 60 years old and about 14% of us will be over 75. Soon, for the first time in history, there will be more people on this planet over the age of 65 than under the age of 5.
